Specification of Letters Patent.

Application filed August 31, 1908.

Patented June 1, 1909.

Serial No. 450,927.

To all whom it may concern:

Be it known that I, JAMEs M. JAooBsnN, a citizen of the United States,residing at Kansas City, in the county of l/Vyandotte and State ofKansas, have invented certain new and useful Improvements inMiter-Boxes, of which the following is a specification.

This invention relates to miter boxes and has for its object to producea device of this character capable of adjustment to determine saw cutsat any angle or at two different angles simultaneously.

A further object is to produce a miter box adapted to accommodate piecesof wood of varying lengths.

A still further object is to produce a miter box embodying a reliablesaw guide adjustable downward to continue its guiding function for thesaw until the latter completes its out.

Another object is to produce a miter box of simple, strong, durable andcomparatively inexpensive construction.

With these general objects in view, the invention consists in certainnovel and peculiar features of construction and organization ashereinafter described and claimed; and in order that it may be fullyunderstood reference is to be had to the accompanying drawings, inwhich:

Figure 1 is a plan view of a miter box embodying my invention, with oneend. broken away. Fig. 2 is a front view of the same. Fig. 3 is acentral vertical section taken on the line III-III of Fig. 2. Fig. 4 isa central vertical section taken on the line lV-lV of Fig. 1. Fig. 5 isa horizontal section taken on the line V-V of Fig. 2. Fig. 6 is avertical section taken on the line VI of Fig. 2. Fig. 7 is a detailperspective view of a part of the bracket carried by the support. Fig. 8is a rear view of a part of the support. Fig. 9, is a rear view of anangle bracket and a horizontally-pivoted bracket pivoted thereby. Fig.10, is an end view of the miter box. Fig. 11, is a rear view of alever-carrying frame forming part of the miter box. Fig. 12, is anenlarged vertical section taken on the line XII-XII of Fig. 9.

In the said drawings 1 indicates a horizontal support such as a piece ofboard of suitable length mounted upon legs 2, and channeled out at itslower front corner as at 3. A bracket secured to said support isconstructed as follows: 4 indicates a central or body portion fittingagainst the under side of the support about centrally of its length. 5and 6 are upper and lower arms projecting laterally from the bodyportion with the fornier fitting against the under side of the support,said arms providing between them longitudinal slots 7. 8 is a flangeprojecting upward from the rear margin of the body portion and providedat its front side with a boss 9 and at its rear side with an upwardlyprojecting car 10 equipped with graduation marks 11 on its faceradiating with respect to a threaded opening 12 extending through theear, the flange and the boss, the upper portion of the ear being roundedconcentrically of such opening, as shown in Fig. 2. To interlock thebracket solidly with the support the latter is recessed in its rear edgeas at 13 to receive the said flange and boss, and is also recessed inits rear edge to receive a pair of ears 14 (one only appearing)projecting upward from arms 5 near the outer ends of the same andextending through said ears 14 and into the support are clamping screws15, standards 16 being mounted on said screws and clamped thereby firmlyagainst the rear edge of the support and ears 14.

17 indicates one of a pair of standards fitting against the rear edge ofthe support and provided with vertical slots, 18 to receive internalthreaded nuts 19, said nuts being provided with flanges 20 to bearagainst the rear sides of said standards and with rectangular extensions21 fitting slidingly in slots 7.

22 indicates clamping bolts projecting through slots 7 and engaging saidnuts and provided with enlargements 23 to clamp the interposed washers24 firmly against arms 5 and 6, the front ends of the screw bolts beingprovided with winged heads 25 by which they may be turned, it beingnoticed that the winged heads are disposed vertically below recess 3 andcan therefore be conveniently gripped and turned although located closeto the bottom of the support.

26 indicates a segment-shaped flange depending from the rear edge ofbody portion 4 of the bracket and provided with a slot 27 extendingconcentrically with threaded opening 12, the lower edge of the flangealso extending concentrically with said opening and having a series ofnotches 28.

29 is a bolt engaging opening 12 and provided with a neck 80 of greaterdiameter than its threaded portion and of smaller diameter than its headand pivoted on the neck is a frame 31, recessed near its lower end as at32 to accommodate the ear 10 and provided on its face with a radial mark33 to register with any of the radiating marks 11' of said ear, as shownclearly in Fig. 2.

34 is a clamping-bolt having its threaded portion of reduced diameterand extending slidingly through slot 27 and engaging a threaded opening35 in the lower end of frame 31, said bolt being preferably provided atits front end with a winged head 36 by whichit may be convenientlyturned for the purpose of clamping frame 31 in a vertical position or atan angle to the vertical. The frame 31 is provided with a notch 37 inits lower end and above the pivot bolt 30, is equipped with a rearwardlyprojecting car 38 to receive a pivot pin or bolt 39, which also extendsthrough one or a pair of ears 4O projecting forward from a lever 41provided at its lower end with a forwardly projecting tooth 42 occupyingnotch 37 and adapted to be held in engagement with any of the notches 28of flange 26, by the pressure of a spring 43 secured to the lever atonev end and pressing forwardly against the rear side of frame 31, asshown clearly in Fig, 3. The frame 31 is provided with a longitudinalslot 44 above its pivotal point and fitting in said slot is therearwardly projecting rib 45 of an angle bracket 46', and securing saidangle bracket at the desired point of vertical adjustment in said slotis a headed bolt 47, said bolt extending through the upwardly projectingarm of the angle bracket, said slot and a washer 47 bearing against therear side of frame 31, a clam ing nut 48 engaging the rear end of theolt for the purpose of clamping the washer and said angle bracket firmlyagainst said frame.

49 indicates a vertical post provided with a reduced threaded end 50engaging an opening 51 in the front end of the horizontal arm of saidbracket and overlying and spaced from said threaded portion is anenlargement 52 of said post.

A bracket pivoted for horizontal movement on said post below itsenlargement 52 and resting on the horizontal arm of angle bracket 46, isconstructed as follows: 53 is a pair of similar angle arms extending atright angles to each other and having their horizontal portionsconnected by a segmentshaped web 54 recessed at its upper side as at 55to receive the head of bolt 47, the nonreduced portion of the webadjacent to said recess 55 being provided with radial marks 56 toregister with a projection 57 on the front end of bolt 47, which bolt isequipped with a clamping-screw 58 for engagement with the underlyingreduced portion of the web, as shown most clearly in Fig. 3. front endof the angle bracket pivoted on bolt The 49, is truncated as at 59 andat the junction of said truncated portion and the arms 53 it is formedwith a pair of vertical posts 60 provided with vertical grooves 61 intheir faces for the reception of the rearwardly projecting flanges 62 ofa V-shaped slide frame 63, the faces of said posts inward of arms 53being recessed as at 64 in order that the outer or front face of the vshaped frame 63 shall be flush with the corresponding faces of the arms53 as shown clearly in Fig. 5, and in order to hold the V-shaped frame63 in the relation described it is provided with a pair of divergingarms 65 fitting slidingly on a pair of vertical posts 66 erected uponarms 53, said posts being reduced at their upper ends to provideshoulders for the support of a cross bar 67 which also fits upon thepost 49, nuts 68 engaging the upper ends of said posts 66 to secure bar67 reliably in position.

69 is a handle secured to the upper end of the V-shaped frame 63 andprovided with diverging arms 70 through which bolts 71 extend to securea pair of guide plates 72 in fixed relation to said frame 63, the armsof the handle serving to space said plate 72 from said frame a distanceabout equal to the thickness of a saw blade, and in order to facilitatethe insertion of the latter between said V-shaped frame and said guideplates 72, the front edges of the latter are bent or flared outward asat 73. To prevent said plates 72 springing outward at their lower endstoo far from said frame 63,1 provide a pair of horizontal guide plates74 which par allel the vertical or depending parts of arms 53 and areprovided at their front ends with tongues 75 which overlap plates 72,and in order to facilitate the insertion of the saw blade between arms53 and plates 74, the upper edges of the latter are flared outward as at76.

To support plates 74 in position, I employ a pair of hangers 77 whichare secured at their lower ends to said plates and have their bodyportions disposed outwardly of the ver tical' plane of the spacesbetween plate 74 and arms 53 and the V-shaped frame 63 and plates 7 2,the upper ends of said hangers terminating in inwardly projecting arms78 fitting upon posts 66 between the cross plate 57 and the clampingnuts 68.

Assuming that it is desired to cut a piece of wood at an angle offorty-five degrees, it is placed upon the support and against the frame31 and the standards 17 and also against the standards 16 if ofsufficient length, it being understood of course, that the standards 17must be shifted from the position shown in Fig. 1 to a position out ofthe plane of the space between arms 53 and guide plates 74 so as not tostand in the way of the saw, it being also understood that the anglebracket 46 is adjusted vertically so as to be disposed as near the topof the piece of wood as possible and then clamped firmly in )osition byclamping bolt 47. The pivoted bracket is then adjusted with its centralgraduating mark 56 in line or register with the projection 57 of bolt 47A saw blade is then slipped between the proper side of the V-shapedframe 63 and the paralleling guide plate 72 and the alined space betweenone of the arms 53 and one of the plates 74:. It is then presseddownwardly onto the piece of wood and reciprocated back and forth to cutthe wood at an angle of forty-five degrees, and to insure a directvertical cut and prevent the accidental disengagement of the blade fromthe guide, the operator may before beginning the sawing operation, forcethe latter, viz. the slide frame 63 and its plates 72 downward so thatsaid frame and plates shall steady the blade for nearly its full width.If it be desired to cut a piece of wood at a greater or a lesser anglethan fortyflve degrees the pivoted bracket mounted on post 49 may beadjusted to the proper angle and then clamped in such position so as toact as a guide for the saw in the cutting operation. If it be desired tocut a piece of wood at right angles to its length, the said pivotedbracket can be adjusted until the desired arm 53 extends atright anglesto the length of the support. If it be desired to cut a piece of wood atright angles to its length but in a plane at an angle to the vertical,the pivoted bracket will be left in the position last referred to andthe upper end of the lever pressed toward frame 31 so as to withdrawtooth e2 from engagement with the notch 28 vertically below pivot bolt30. While the lever is thus held the frame 81 can be swung pivotally tothe ri ht or to the left and when it has been adjusted to the properangle the lever is released to permit spring 43 to rock it and cause itstooth to engage the registering notch 28 of flange 26. If desired thepiece of wood can be cut at an angle to its length and also at an angleto the vertical by the proper adjustment of the pivoted bracket carriedby bracket 46 and of the swing frame 31, it being noted in thisconnection that if the block is a short one, that is, of only suflicientlength to find a bearing against frame 31 and the'standards 17 thelatter can likewise be pivotally adjusted to avoid occupying the path ofthe saw blade. The same adjustment of the standard 17 may be made wherea short block is to be cut vertically but at an angle to its length.Standards 16 ordinarily occupy vertical positions, being pivotallymounted so as to be capable of being folded against the rear side of thesupport when not in use, as there is never any necessity for disposingsaid standards at an angle when the miter box is in use.

From the above description it will be aparent that l have produced amiter box e1nliodying the desirable features enumerated in the statementof the object of the invention, and that the latter is susceptible ofmodification in various particulars without departing from the principleof construction involved.
